xcube-cci fetches metadata from odp incorrectly

[AliceBalfanz]

When opening a dataset with xcube-cci:
I request this PERMAFROST dataset, which based on the metadata should have data in the requested time:

dataset = store.open_data('esacci.PERMAFROST.yr.L4.GTD.multi-sensor.multi-platform.ERA5_MODISLST_BIASCORRECTED.03-0.r1',
                          time_range=['2014-01-01','2016-12-31'])

It "pretends" to have data in it: 3 time stamps. but then when I run dropna for all variables in time, nothing is left. All variables are empty:

@TonioF your response about this:

Rather: The wrong metadata is used.

There is a problem with fetching the correct metadata from ODP. This is a major blocker.
